我已经编写了从摄像机捕获图像的代码,我想将该图像保存在文档目录中。我已经做了代码,但我认为该图像不存储文档目录。因为当我获取图像的摄像机图像不在文档目录,我的代码:未保存在文档目录中的摄像机图像
- (IBAction)takePhoto {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:YES completion:NULL];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *cameraImage = info[UIImagePickerControllerEditedImage];
self.tempView.image = cameraImage;
[_chosenImages addObject:_tempView.image];
[picker dismissViewControllerAnimated:YES completion:NULL];
}
id n = [array3 lastObject];
NSLog(@"The id is=%@",n);
NSError *error;
NSString *aDocumentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *dataPath = [aDocumentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%@",n]];
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error];
NSInteger anIndex = 0;
for (UIImage *anImage in _chosenImages) {
NSString *anImageName = [NSString stringWithFormat:@"%d.png", anIndex++];
NSString *anImagePath = [NSString stringWithFormat:@"%@/%@", dataPath, anImageName];
NSLog(@"the path is=%@",anImagePath);
NSData *anImageData = UIImagePNGRepresentation(anImage);
[anImageData writeToFile:anImagePath atomically:YES];
这是什么说法给你,的NSLog(@“路径=%@”,anImagePath) ;和NSLog anImageData来检查数据是否为空 – satheeshwaran
我在iPhone上测试我不知道.. – Nasir
我认为问题不在于存储代码..但是有了取回代码..您能否展示如何获取来自文件目录的图像? –
